I don't want arms supply anymore, how do I cancel my subscription?

Now that the game offers a subscription for the Arms Supply I am not sure if there is an option in the game to cancel it. However subscriptions are usually handled via your app store (itunes / google play store). Go you your app store app and check in your account for 'subscriptions'. If it is listed there you should be able to cancel it that way. If not then please contact the in game support to ask them to cancel it.
